This pointer was being used for two reasons: pnv_phb4_update_regions() was using it to access the PHB and phb4_realize() was using it as a way to determine if the PHB was user created.
We can determine if the PHB is user created via phb->pec, introduced in the previous patch, and pnv_phb4_update_regions() is no longer using stack->phb. Remove the pointer from the PnvPHB4 device.
